Cold Storage Warehouse Types Based on Refrigerating
Temperature Range
High
temperature walk-in cooler cold storage warehouse -
Class L, Temperature Range: +5℃~ -5℃. The
storage purpose of this refrigerator
cold room is
for refrigerated storage of food like vegetable,
fruit, egg, pharmaceutical material, floral, wood
and other things suitable for this temperature
range.
Medium temperature walk-in freezer cold
storage warehouse - Class D, Temperature
Range: -10℃~ -18℃. The storage purpose of this
freezer cold room is for frozen storage of food like
meat, seafood and other things suitable for this
temperature range.
Low temperature walk-in freezer cold storage
warehouse - Class J, Temperature Range: -23℃~ -28℃.
The storage purpose of this deep freezer cold room
is for the frozen storage of ice cream and other
deep frozen food etc.
Ultra low temperature walk-in freezer cold
storage warehouse - Temperature Range:
≤-30℃. The
storage purpose of this ultra low temperature cold
room is mainly for fast frozen food, industrial
laboratory test room, medical treatment, blood bank,
etc.
To design a
cold storage
plant, besides considering the size of the cold
storage warehouse, the important thing you need to
consider for a refrigerated warehousing project is to select the suitable refrigeration
temperature of the refrigerated warehouse. The
temperature of the cold room plant shall not be too
high or too low.
2. Cold
Storage
Warehouse Types Based on Installation Structure:
Civil
construction refrigerated warehouse - The space
enclosing structure wall material of the cold store
room is made of brick and the heat insulation
material is made of sprayed polyurethane (PU foam).
To build a civil
construction refrigerated warehouse or assembling
refrigerated warehouse, you need to consider your
local building construction and local building cost
on the refrigerated warehousing storage project.
We prefer to build a
assembling refrigerated
warehouse because the prefabricated modular cold
room panel (insulated sandwich PU foam panel) can be
installed and disassembled at any time and it is
very convenient to move the cold storage warehouse
to another installation place.
Refrigerated
Storage Requirements of Food and Physical Nature
Before you
decide to design and build a
walk-in cooler or
walk-in freezercold storage warehouse, you need to
first know what is the best storage temperature of
the cold room plant to store your food material or
other materials. In this way, you can avoid to
build a refrigerated warehouse which is not cool
enough to store goods or is too freezing and to
freeze & destroy
the food and waste investment money on cold storage
plant project cost because the colder temperature
requires bigger powerful compressor and
refrigeration system.

The above form shows the
best suitable temperature for the refrigerating
storage of different food materials of fruit,
vegetable, meat, drink beverage etc.. So you can
take the listed temperature range as reference to
design and build your walk-in cold storage warehouse
and refrigerated warehouse for your restaurant,
hotel kitchen, supermarket, chain store, vegetable &
fruit market and other cold storage logistics plant.
